Benshan Mine was known for producing a unique gold-copper ore mixture rather than pure gold veins.
The mine utilized a complex 'square-set' timbering method to stabilize tunnels, a necessity due to the soft, unstable mountain rock.
During World War II, the site was converted into a prisoner-of-war camp by the Japanese military.
The mining tunnels span multiple levels, with the 'Number 5' tunnel being the primary accessible point for modern educational tours.
Mining operations were officially shuttered in 1987 due to declining ore grades and rising operational costs.
The distinct yellow and reddish-brown coloration of the surrounding stream, known as 'Golden Waterfall', is a direct result of acidic mine drainage mixing with iron minerals.
Benshan Mine is the former primary extraction site of the Jinguashi Gold Ecological Park in Ruifang, New Taipei City. It represents the historical core of Taiwan's gold mining industry, which peaked during the Japanese colonial period. The site features preserved tunnels, ventilation shafts, and mining infrastructure that demonstrate early 20th-century extraction techniques. Visitors can access the 'Gold Mine Museum' trail, which leads to the main entrance of the Benshan Number 5 Tunnel. The area is characterized by its mountainous terrain and remnants of ore processing facilities, including the famous Remnants of the 13-Level Administration and Smelting Plant nearby. Extensive excavation once made this the most productive gold mine in East Asia.
The elevated lookout point near the tunnel entrance, which provides a panoramic view of the Pacific Ocean and the surrounding valley.
Wear sturdy, closed-toe walking shoes as the terrain consists of uneven stone paths and gravel trails.
Bring a portable fan or cooling towel, as the area experiences high humidity and significant heat trapped in the mountain valleys during summer.
Hydrate well before starting the hike, as facilities for water are limited once you ascend toward the tunnel entrance.
Attempting to climb or enter restricted or fenced-off tunnel entrances, which are structurally unsafe and prohibited.
The outdoor trail areas are generally open year-round, but access may be restricted during extreme weather events like typhoons.
Remain on designated paths; the surrounding mining site contains unstable ground and restricted areas that are off-limits for safety.
